VEHICLE-WHEEL.

Specification of Letters Patent.

Application filed April 11, 1917. Serial No. 161,174.

To all whom it may concern: a

. Be it known that I, JOHN W.'MART1N, a citizen of the United States, and a resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Vehicle- Wheels; and I do hereby declare the following to be a full, clear, and exact description thereof. a

This invention relates to vehicle wheels, and more particularly to that class of wheels having pneumatic internal cushlons, and has for one of its objects to provide a device of this character thatwill have a novel form of drive hub and plates for engaging the same.

Another object. is to provide novel and improved means for retaining the internal cushions in place.

Other objects and advantages such as efliciency, simplicity, durability, and the general improvement of the art will be brought out in the following specification.

In the drawings, I have illustrated several preferred forms of my invention, although it will be understood that I do not wish to be limited to the exact construction shown, since changes may be made withinthe skill of a mechanic in the art, and such changes are to be considered within the scope of the appended claims.

Figure 1 is a side elevation of my devlce with the cover plate removed,

Fig. 2 is a cross section through the complete assembled wheel,

Fig. 3 is a cross section of an assembled wheel similar to that shown in Fig. 10,

Fig. 4: is an enlarged detailed view of the hub member,

Fig. 5 is an end view of the hub drive,

Fig. 6 is a detailed sectional view of one of the lugs or spurs on the hub,

Fig. 7 is a detailed end plan v1ew of the same,

Fig. 8 is a detailed side elevation of the same, 7

Fig. 9 is a side view of one of the cover plates,

Fig. 10 is a side elevatlon of a sllghtly modified form of a wheel constructlon.

Referring more particularly to the drawings the device is designated as a whole by the letter A and comprises a tire 10, a rim 12for locking them in position,

Patented Got. 22, 1913.,

bushing 15, which has at each end or termi- 18 is secured thereto by screws 19, and bearing'balls 20 are mounted in the groove between the plate and end face.

Spokes 13 are secured in the sleeve 15, and support a felly 22 for the internal cushion 12.

Side plates 23 each having annularly arranged sockets 21 for the reception of the spurs 16 and a central aperture 25 extend around the hub 14 and have annular transversely extending flanges 26 adapted forengagement with the flanges 27 of the cushion the flanges 26 being further adapted for supportin a felly 28 having spokes 29 therein, which felly secured in place by bolts 21.

The spokes 29 support, and have their outer ends secured in the rim 11 of the usual construction for supporting a tire 10 which may be of any ordinary construction, preferably solid.

The device when assembled is adapted to be supported on an axle 30 having an inner flange 31 with an annular groove 32 in which are mounted bearing balls 33 held in place by plate 34. A washer 35 0f similar construction to the flange 31 is mounted on the free end of the axle and abuts against the shoulder 36 on the axle and is held in position by a nut 37 such flange and washer being of such size as to take care of side thrusts.

Referring to Figs. 3 and 10, I have shown a wheel embodying the same structure as that shown in Figs. 1 and 2 with the exception that it is provided with a felly 43 circumferentially undulated so as to provide alternating depressions 43 and raised portions 43". It will also be noted that I have dispensed with felly 28 and spokes 29, the undulating felly 43 forming a seating for the inner cushion 12 and also engaging the outer tire 10. The raised portions of the felly 43 form a support for the inner cushion 12? as is clearly shown. This form of felly will provide a broken contact in order to make the wheel more flexible. The several other parts of this form of wheel being similar to that shown in the other figures of the drawing will be designated by like reference numerals having the exponent 7;.

It Will thus be seen that the wheel constructed in accordance With my invention Will protect the air cushion from punctures or other injury, While said cushion will absorb and overcome all shocks.

Having thus fully described my invention, What I claim is:-

1. A vehicle Wheel comprising a hub, spokes in said hub, a felly supported by said spokes, said folly being circuinferentially undi'ilated to provide alternating depressions and projections, a pneumatic cushion supported by said felly, a second felly sur rounding said cushion, side plates on each side of said Wheel and secured to said last,-

named felly, loeking'flanges on said plates engaging said cushion to secure it in place, said side plates being spaced from said hub member and having apertures therein adjacent said hub, lugs on said hub adapted to loosely engage with saidapertures, and means on said hub engaging said plates to prevent their accidental lateral displacement.

2; A cushioned wheel comprising a hub adapted to be rigidly secured to an axle, spokes in said hub, a felly supported by said spokes, said felly being circumferentially undulated to provide alternating depressions and projections, a tubular pneumatic cushion loosely supported by said felly, a second felly surrounding said cushion, side plates on each side of said Wheel and secured to said last named felly,

Copies of this patent may be obtained for flve cents each, byaddressing the locking flanges on said plates engaging said cushion to secure it in place, said side plates being spaced from said hub member and said-axle and having apertures therein adjacent said hub, lugs on said hub adapted to loosely engage Within said apertures, and means on said hub engaging said plates to prevent their accidental lateral displacement.

3. A vehicle Wheel comprising a. hub, spokes in said 11ub,'a. felly supported by said spokes, said folly being circumierentially undulated to provide alternating depressions and projections, a pneumatic tubular cushion member loosely supported onthe projections of said i'elly, a second telly SHBI'OUHCl'IILg sald cushion, SlClGi plates on each side of said wheel and secured to said plates engaging said cushion to secure it in place, said side plates being spaced from said hub member and having apertures therein adjacent said hub, means on said hub adapted to loosely engage Within c JOHN W.
